DKhen · 2024-10-12T09:27:21Z

Describe the Bug

ive just installed Version 4.0.0, set up the bot from scratch but still receiving the Same error as in the old Issue.

Bot: Swotchbot failed BLEpushChanges with
BLE Connection, Error Message: "Cannot read properties of undefined (reading 'press') "

To Reproduce

install Version 4.0.0
Setup bot with BLE
tap Switchbot bot with Firmware v6.6

Expected Behavior

properties can be read and makes a press

Providing no config?

Also you have this installed on portainer. My guess is that that could be causing the issues.

Sorry, it didnt show up, here it is:

The error also occurs if I use the Plugin outside of docker.

donavanbecker · 2024-10-12T10:50:31Z

Does everything work fine with OpenAPI?

donavanbecker · 2024-10-12T10:51:20Z

Update your deviceId to C73234350B5C

DKhen · 2024-10-12T11:25:01Z

Isnt OpenAPI exclusive to use with the Switchbot Bridge? I just got the bot.

Changed deviceId but no difference.

DKhen · 2024-10-12T11:26:38Z

New error Message:

donavanbecker · 2024-10-12T12:43:55Z

Yes you need a Hub to use bot with OpenAPI

donavanbecker · 2024-10-12T12:46:59Z

New error Message:

This happens when the plugin cannot receive serviceData (BLE Data) from the device.

If you cannot push a command, I am not surprised that you weren't able to receive as well.

donavanbecker · 2024-10-12T12:49:25Z

The error also occurs if I use the Plugin outside of docker.

Have you installed all prerequisites of node-switchbot and noble.

DKhen · 2024-10-12T16:33:00Z

Yes I have, im trying also some scripts with noble with discovering bluetooth devices, and that seems to be working.
Is there a discord where we could discuss this?

DKhen · 2024-10-12T18:26:35Z

directly from homebridge console:

const noble = require('@stoprocent/noble');

const targetAddress = 'c7:32:34:35:0b:5c';

noble.on('stateChange', (state) => {
    if (state === 'poweredOn') {
        console.log('Bluetooth is powered on. Starting scan...');
        noble.startScanning([], false);
    } else {
        console.log('Bluetooth is not powered on. Stopping scan...');
        noble.stopScanning();
    }
});

noble.on('discover', (peripheral) => {
    const discoveredAddress = peripheral.address.toLowerCase(); // Normalize to lowercase
    if (discoveredAddress === targetAddress) {
        const advertisement = peripheral.advertisement;
        const manufacturerData = advertisement.manufacturerData;

        let deviceName = 'Unknown';
        if (manufacturerData) {
            // Extract device-specific name from manufacturerData if localName is undefined
            deviceName = `SwitchBot_${manufacturerData.toString('hex').slice(0, 12)}`;
        }

       console.log(peripheral);
       console.log('Discovered target peripheral:');
       console.log(`  Name: ${deviceName}`);
       console.log(`  Address: ${peripheral.address}`);
       console.log(`  RSSI: ${peripheral.rssi}`);
       console.log(`  UUID: ${peripheral.uuid}`);

But if I try this using node-switchbot:

import { SwitchBotBLE } from 'node-switchbot';
import noble from '@stoprocent/noble';
const switchBotBLE = new SwitchBotBLE({ noble });

switchBotBLE.discover().then(() => {
  console.log('The discovery process was finished.');
});

switchBotBLE.discover({
  duration: 5000,
  quick: true
}).then((device_list) => {
 console.log(device_list);
}).catch((error) => {
  console.error(error);
});

i get

The discovery process was finished.

@donavanbecker using noble, i managed to send the trigger command to the bot, eventually this might help you with finding the error? i have tbh struggle to see through this project 😅

const noble = require('@abandonware/noble');
const targetAddress = 'c7:32:34:35:0b:5c';

noble.on('stateChange', (state) => {
    if (state === 'poweredOn') {
        console.log('Bluetooth is powered on. Starting scan...');
        noble.startScanning([], false);
    } else {
        console.log('Bluetooth is not powered on. Stopping scan...');
        noble.stopScanning();
    }
});

noble.on('discover', (peripheral) => {
    const discoveredAddress = peripheral.address.toLowerCase();
    if (discoveredAddress === targetAddress) {
        console.log('Discovered target peripheral:', peripheral.advertisement);

        console.log('Attempting to connect...');
        peripheral.connect((error) => {
            if (error) {
                console.error('Failed to connect:', error);

            // Add a small delay before interacting
            setTimeout(() => {
                sendCommandToSwitchBot(peripheral);
            }, 1000); // Delay for 1 second
        });

        // Handle disconnect
        peripheral.once('disconnect', (error) => {
            if (error) {
                console.error('Disconnected due to error:', error);
            } else {
                console.log('Peripheral disconnected');
            }
        });
    }
});

function sendCommandToSwitchBot(peripheral) {
    peripheral.discoverAllServicesAndCharacteristics((error, services, characteristics) => {

Thanks @DKhen! When I have time I will take a look. But if you want to open a PR to make it better, by all means.

DKhen · 2024-10-17T19:33:00Z

oh that was no critism for your project, its just my own stupidness lol :D i will give it a try, but im sure in mean time you already fixed it haha

donavanbecker · 2024-10-17T20:28:13Z

I wasn't taking it as critism. I self taught myself how to code.... so it probably could be better ha.

DKhen · 2024-10-17T20:36:23Z

Ah okay nice, in fact i develop with php, but I find it hardly to get into typescript especially with such huge projects

donavanbecker · 2024-10-19T04:13:32Z

@DKhen are you on the homebridge discord server?

Not yet, you got a link somewhere?

Discovered target peripheral:
  Name: SwitchBot_6909d9343130
  Address: d9:34:31:30:3f:45
  RSSI: -70
  UUID: d93431303f45
  Advertisement: {
  localName: undefined,
  txPowerLevel: undefined,
  manufacturerData: <Buffer 69 09 d9 34 31 30 3f 45 36 8c>,

  serviceUuids: [],
  solicitationServiceUuids: [],
  serviceSolicitationUuids: []
}

But, via the node-switchbot lib itself, it seems to timeout:

homebridge@craptop:/var/lib/homebridge/node_modules/@switchbot/homebridge-switchbot $ node w-switchbot.mjs 
Error: No devices found during discovery.
    at Timeout.<anonymous> (file:///var/lib/homebridge/node_modules/@switchbot/homebridge-switchbot/node_modules/node-switchbot/dist/switchbot-ble.js:184:32)
file:///var/lib/homebridge/node_modules/@switchbot/homebridge-switchbot/node_modules/node-switchbot/dist/switchbot-ble.js:184
                        reject(new Error('No devices found during discovery.'));
                               ^

Error: No devices found during discovery.
    at Timeout.<anonymous> (file:///var/lib/homebridge/node_modules/@switchbot/homebridge-switchbot/node_modules/node-switchbot/dist/switchbot-ble.js:184:32)

Node.js v22.12.0

If this seems like a separate issue LMK, happy to make a separate issue :)
